some al'ipearauce, and which will not he at footed y the swellingand shrinking oi the wooden core within it.

The above objects are accomplished hy my invention, one embodiment of which is he"? inafter disclosed.

Generally stated, the column consists of a series of wooden staves so arranged to form an annular hody, said staves being socured at their ends and spirally wound with a hinding material, all of which is covered with a plaster or plastic coating. The strives of the column are interiorly supported at suitable points oi their length and at each end, where they are connected to an ornamental base and cap-piece of any desired contour.

Reference is to he. had to the accompanying drawings, forming a part ol this specilication, in which similar characters of relerence indicatecorresponding parts in all the figures.

Figure l is a longitudinal vertical sectional view of the completed column. Fig. 2 is a section on the line 2 2 oi Fig. ];and Fig. 3 a plan view of the column with the top cap removed, parts being in section.

The numeral base or foundation upon which mounted an apertured ornamental supporting-block 2, having secured to thc'center of its upper face an aperture l hloek of such size as to snugly lit the interior ol the column-core. The slaves 4, forming the core, are beveled at,

each edge for about hall" their thickness, the

degree ol hevel depending upon the size oi the column desired. it will he seen by this construction ol the slaves that when placed with their beveled faces in. contact a V- sha )ed opening 5, extending to substantially hal' their thickness, is left between the joints, and their contacting faces are radial of the column The staves are secured to 1 indicates a suitable hollow gether by nailing or otherwise securing them l about any desired number of apertured supporting-hloclts 3", similar to the hloclr 3, and l are held together at their ends by eorruga ted metal fasteningplates 6, connecting the permitting the sepa- 3. The holjoints l the slaves and ratior. i llttfi, as shown in Fig. low. \ixloden eore fOJlP-Qll by the slaves is spi'rall wrapped with a cord or rope 7 and cover .l by casting or molding a p aster or.

l ilaslie nuiterial 7 ahout'it. The top of the l column is provided with an apertured ornal mental cap 8, supporting a hollow block 9 and having secured to the center ol its hottom lace an apertured block 3 ,projecting This part of the construction corresponds exactly to the manner in which the hase-hloek2 fastened to the hottom end of the column. A slight change is,

however, made overthe base-block 2 in the cap 25 by )roviding tric annular groove 10, into which an enlarged upper end of the column rests.

l u the construction of the column after the staves are fashioned up and secured together by nailing or otherwise securing them to the rugated fasteners 6 the wooden core is thoroughly soaked in water, which swells the wood and securely closes the cracks at the 1 joints of the sta'ves. The core is then coated on the outside with a preparationas grease, l soap, or parallin or other )reparation of like l p1alities--in order that the shaves and the plaster coating to be applied may readily separate in the unequal expansion or contraction of the plaster and core in drying out, thereby permitting them to act indemndent of rich other. While the core remains wet the heme, twine, or rope 7 is tightly and spi- I rally wound about them. The wooden core i or shaft is then stood on end and molds made I in halves somewhat larger in diameter placed about it, leaving a concentric space into which the plaster or plastic material is poured. After the outer coating, which m he colored, if desired, becomes sul'l'it'ly hard the mold reinoved, and if any emishcs appear on the surface of the coat-- ,5 he column is placed in a lathe and the imperfections corrected with any suitable. device. l have found it desirable to use a coloring iuatter in rnos cases in the )laster I and. to apply coating 0* hot linseed-oil to lithe some while the column remains in the lathe.

1 blocks 3" and. driving into the ends the cor the latter with a concenbut the'plaster is prevented from passing to latedand soon dries out, allowing the staves After the body of the column is finished it is secured to the base 2 and capg 'b nailing it to the blocks 3, 3 and 3 as clear y shown in Fig. 1. The \l-shapedgrooves between the staves form a tie for and permit the plase ter to enter and firmly embrace each stave;

the interior of the column by the contacting beveled faces of the sta v es, which are, as be fore stated, closed tightly by reason of their water-soaked condition. By havin a hole entirely through the column it is we I ventientering thiekness on opposite edges, leaving outer V-shaped grooves at their joints, means for connecting the staves together comprising apertured blocks and corrugated fasteners, a rope spirally embracing the staves, a plaster covering the staves and rope and entering the V-shaped grooves, and an apcrtu'red base' bloek and cap secured to the ends 01" the column.

' 2. In a column, a series of staves arranged to form a core, said staves being beveled for a portion of their thickness at opposite edges, leaving outer V shaped grooves at their 1 essees joints, means for securing the staves together, and a plaster covering the stavesandthe grooves for the purpose specified.

3. In a column, a series of staves arranged to form a core having their faces of contact radial of the column, said staves being beveled for a portion of their thickness only, leaving outer V-shaped rooves at their joints, a rope. spirally ernl aracing the core, and a plaster entering the V-shaped grooves, and coverin the rope and core.

4. In a co urnn, a series of staves, arranged to form a core having their faces of contact radial of the column, said staves being beveled for a portion of their thickness only, leaving outer V shaped. grooves at their joints, a plaster entering the V -shaped grooves and covering the core and pre araion between the plaster and core for a low-- ing their ready separation for the purpose described' 5. In a column, a series of wooden staves annularly arranged to form a core, said staves being beveled for a portion of their thickness at opposite edges, leaving outer V-shaped grooves at their joints, means interior of and at the ends of the core for securing the staves together, a plaster covering the core, entering the grooves to form a tie,

and an apertured base-block and cap having extensions fitting into the coluinniand se,- cured thereto.

In testimony whereof I have signed my muneto this specification in the presence of two subscribing witnesses.
